For those who don’t know him Kouji Mori was a close friend of Miura. they met in highschool and share theor passion of becoming mangakas and pushed themselves to be the best. And the most important thing here is that there was a bit of rivalry going on between them, in fact Mouri even went on to become the inspiration behind Griffith. In their youth Miura was deeply affected by their meeting and said Mori was really charismatic.
They still remained friends while both achieved their dream of becoming mangakas. If there is even one person who could ensure Miura’s vision, that would be him. Life takes strange turns.
If any of you is interested I deeply recommend you to read Holyland by Kouji Mori, easily the best manga I’ve read about street fights it’s realistic abd left me with a strong impression.
